PATENT-ED PR 1 1 1m SHEET 5 [IF 6 FZGL 10 lflfw DRINK DISPENSING AND MIXING SYSTEM This invention relates to a construction for preparing mixed drinks. The invention will be particularly described, and finds maximum utility, when used for preparing alcoholic beverages. It will be understood, however, that the features of the invention may beapplied for the preparation of other mixtures which call for the use of varieties of ingredients and variations in the amounts of ingredients.

In the preparation of alcoholic beverages, a variety of ingredients is often called for. The recipes for drinks also specify use of the ingredients in certain proportions. It is a well-known fact that some drinks are very difficult to prepare properly unless the proper ingredients, in proper proportions, are employed.

It is difficult for any individual to achieve sufficient skill for properly preparing a large variety of drinks which require multiple ingredients. Thus, one cannot be expected to memorize the ingredients for several drinks, and it is inconvenient and time-consuming to continuously refer to recipe books for alcoholic beverages. A possibly more serious ,difficulty arises because of the inability to properly control proportions of ingredients, and in many cases, even small variations from a recipe can destroy the appeal of a mixed drink.

It is a general object of this invention to provide a construction which is designed for the preparation of a large variety of mixed drinks. 7

It is a more specific object of this invention to provide a construction which includes means for dispensing desired ingredients from a selection of many ingredients, while also dispensing the desired ingredients in precise amounts, whereby mixed drinks requiring a plurality of ingredients in specific proportions can be properly prepared.

It is a still further object of this invention to provide a construction of the type described which includes the unique combination of selector means, and dispenser actuating means associated with the selector means, whereby an extremely large number of combinations of ingredients and proportions can be incorporated in a construction which is highly compact and which includes a highly reliable and efficient operating system.

These andother objects of this invention will appear hereinafter and for purposes of illustration, but not of limitation, specific embodiments of the invention are shown in the accompanying drawings in which:

The construction of this invention generally comprises a housing defining a plurality of individual compartments for holding a variety of ingredients to be used in the preparation of mixed drinks. Each compartment is provided with a dispensing means which is individually operated when ingredients are to be removed from that compartment. Each compartment communicates with outlet means and the outlet means are situated at a common location so that the various ingredients can be collected in a common container.

The invention contemplates the use of a selector means which may display the names of or a code enabling an individual using the construction to select the drink. desired. Actuating elements are associated with the selector means so that these elements will be positioned in accordance with the drink selected. A drive arrangement is then actuated whereby certain ones of the actuating means will operate dispensing means for certain compartments. The actuating means and dispensing means are designed so that the ingredients from the particular compartments will be delivered in particular proportions. The construction of the invention may be manually operated, however, a

motor driven arrangement is provided whereby maximum convenience and accuracy can be achieved.

In the preferred form of the invention, the individual drink dispensing compartments are associated with larger containers used for replenishing the ingredient supply. The construction is designed so that the replenishing action takes place automatically whenever ingredients are removed from aparticular compartment.

The use of motor driven means for achieving the dispensing action also provides a highly convenient means for incorporating a mixing unit in association with the construction. Thus, the same motor used for achieving the movements necessary for the dispensing operation can be used to drive a mixing device located on the base of the construction.

The construction shown in the accompanying drawings comprises a base portion 10 having an upright member 12 mounted thereon. The member 12 supports a horizontally disposed plate 14 which in turn supports an annular insulating jacket 16. Upper and lower decorative strips 18 may be secured to the jacket adjacent the annular shoulders 20. i

An annular cover 22 defining a downwardly extending rim 24 is fit around the jacket'at the top of the construction. This extends over a plurality of liquid containing cells. As best shown in FIGS, thecells consist of 12 large cells 26, two sets of three smaller cells 28,

. be provided beneath these cells.

The outlet openings 32 of the large cells 26 communicates by means of passages 38 with a check valve structure 40. As shown in FIGS. 9 and 12, the check valve receives a ball 42 which when seated blocks the passage 44. This passage defines a threaded inner wall to provide for attachment of the externally threaded valve. A gasket .46 is attached to the base 48 of the I rather than a side inlet.

The valves 40 and 56 each communicate with the interior of a dispensing compartment 58. In the embodiment'shown, the 12 large cells 26 communicate with a compartment 58 in the outer ring of compartments through valves 40. The smaller cells 28 and 30 each communicate with one of the compartments in the inner ring by attaching pipe sections 53 of appropriate length to valve 56. The compartments 58 and associated supply cells may be molded as an integral construction, for example using-plastic molding techniques. Appropriate finishing, for example drilling of the passages 38, may be undertaken after molding.

The compartments 58 each comprise a reciprocally movable piston assembly comprising piston head 60 and piston rod'62. Thepiston head is preferably formed from Teflon or a similar low frictionmaterial so that a 68 which includes downwardly extending arms 70.

These arms are received in grooves 72 defined by an inner cylinder 74 which is secured in each compartment. Each cylinder 74 defines an annular flange 76 which seats on a shoulder 78 defined around the upper edge of each compartment. The inner cylinder 74 may be permanently fixed in position in each compartment, for example by means ofa suitable adhesive.

Each inner cylinder 74 defines a transverse wall 80 having a central opening 82 for receiving the piston rod 62. A spring 84 is interposed between the transverse wall 80 and the transverse section 68 of the tappet. This spring serves to normally hold the piston head 60 in a raised position in each compartment as illustrated in FIG. 7.

Each of the tappets 66 carries an upwardly extending arm 86. The respective arms 86 serve as actuating means for dispensing liquid from the compartments 58. The actuating means are adapted to operate in conjunction with downwardly extending pins 88 which are attached to a rotatably mounted upper plate 90.

The plate 90 is attached to an annular ring 92 by means of fasteners 94. The ring 92 includes an externally threaded portion which provides for removable attachment of the ring to cylinder 96. The cylinder 96 extends downwardly within the centralopening defined between inner cylindrical wall 98 formed in the molded unit which carries the compartments 58 and the supply cells for the compartments. The cylinder 96 and associated plate 90 are mounted for rotation and reciprocal movement relative to the inner cylindrical wall 98.

Rotation of the plate 90 is achieved by means of a handle 100 attached to the top of the plate. The handle 100 also serves as a means for attachment of a vertically extending rod 102. The rod 102 is attached to a piston head 104 which is movable within the cylinder 106. The interior of the cylinder 106 communicates through opening 108 with a vacuum pump 110. The pump 110 is operated by means of the motor 112 mounted in the interior of the supporting cylinder 12.

The supporting cylinder 12 also provides space for holding batteries 114, and a suitable jack may be provided for recharging purposes. In addition .to using battery power, the motor 112 could be connected to a conventional electrical outlet.

The motor 1 12 also serves to drive shaft 1 16 which is connected through clutch 118 to the pulley 128. The belt 122 mounted on the pulley extends to pulley 124 (FIGS. 1 and 2) for driving the element 126. Containers to be used for mixing purposes may be provided with recesses having a cross section corresponding to that of the element 126 so that the mixing can be accomplished automatically on the base of the construction.

The ingredients to be dispensed in a particular instance are delivered through discharge spout 128 defined in the bottom wall of chamber 130. The ingredients are delivered to this spout from the assembly 132 mounted; within the chamber on the bracket 134. The assembly 132, as best illustrated 'in FIG. 20, consists of upper plate 136' and lower plate 138 attached by means of bolts 140..The upper plate 136 defines a plurality of tubular inlets 142, and tubular outlets 144 are defined by the lower plate.

A plurality of passages 146 are defined by aligned portions of the upper and lower plates. Each of these passages holds a spring 148 which normallyforces a ball 150 into seating engagement to block communication between the opening 152 in each inlet member 142 with the passage 146.

The supporting member 12 carries a switch 154 which must be turned on to provide for operation of the 5 milliamp gallery lights, which may be located at various points, for example in association with the plate 14 or the cylinder 12. The motor 112 will operate when 7 one of the push buttons 156 and 158 is engaged. The push button 156 is engaged after the selector plate 90 is located in the desired position. A second one-way clutch 160 transmits drive from the motor 112 to the vacuum pump 110. The clutch 118 is disengaged dur- The motor 112 is a reversible motor and, therefore, it

will rotate in the opposite direction when the push button 158 is'engaged. The clutch 118 then provides for operation of the mixing mechanism while the clutch 160 is disengaged so that the vacuum pump will not operate when mixing is desired.

Electrical leads may also be connected to ring contacts 162 and 164 which are positioned on the insulating. member 166 supportedby the transverse wall 168 attached to cylinder 106 (FIGS. 5 and 7). Spaced apart contacts 170 are mounted opposite the ring contacts and the contact portions of bulb 172 are connected between these spaced contacts. The bulb is located in receptacle 174 provided in the handle 100. A cap 176 provides access to the receptacle for replacing the bulb.

This arrangement provides a readily visible means for determining whether the piston head 104 bottoms during a dispensing operation. Thus, the contacts 170 will engage the ring contacts 162 and 164 when a complete stroke occurs turning on the bulb 172.

In the use of the construction described, the various cells are filled with different ingredients for mixed drinks. The specific ingredients to be used will depend upon the selection of drinks to be made available. As illustrated in FIG. 3, the cover 22 is inscribed with the names of a variety of drinks, the particular example involving 40 different drinks. The pins 88 are located on the selector plate 90 to provide dispensing action from particular cells when the selector plate is in a particular position.

It will be noted when considering FIGS. 7 and 9, that the pins 88 are of different lengths. Since the stroke of the piston head 104 which controls the movement of the pins is uniform, the length of the pins will determine the extent of movement of the piston heads 60 in the dispensing chambers 58. The pins 88 thus provide a highly dependable means for controlling the proportions of ingredients in a particular drink. The dots 178 shown in FIG. 3 indicate the positions of pins on the selector plate 90, and it will be apparent that by providing pins of different length in different positions, a very large number of combinations can be worked out. The illustration of 40 different combinations in' the drawings is by no means an upper limit of possibilities. It will also be appreciated that a limited number of cells could be filled, and the apparatus could then be used for making'only a smaller selection of drinks. Suitable instructions can be provided so that one can determine which cells should be filled in order to provide a particular drink.

The particular dispensing action is also controlled by the position of the arms 86 on the tappets 66. As shown in FIGS. 13 and 17, one tappet may have an arm 86 at an extreme position. FIGS. 14 and 18 illustrate an arm 86 in an intermediate position, and in FIGS. and 19, the arm 86 is centrally located. Since the arms 86 in the first two tappets can be either to the left or right of center, five different positions are provided. This, of course, provides additional possibilities for varying the dispensing action for a particular position of the selector plate. Since the tappets and pins can be designed for removal and replacement, it will be appreciated that variations can be made even after the structure has been built, for example if a particular change in a recipe were desired.

The selector plate preferably supports a bracket 180 on its underside. The bracket holds a spring loaded detent pin 182, and this pin engages grooves 184 defined by the inner surface of the cell wall 186. This arrangement insures that the selector plate 90 will be in proper alignment when the arrow 188 on the selector plate is moved opposite one of the drink selections.

When the selector plate 90 is in the proper position, a mixed drink is obtained by depressing the push button 156. This results in operation of the vacuum pump whereby the piston head 104 moves downwardly along with the selector plate and associated pins 88. Certain ones of these pins will engage the upstanding arms 86 associated with particular dispensing compartments 58. The piston heads 60 in these compartments will move downwardly depending upon the length of the particular pin engaging the arm 86 for that compartment.

The downward stroke of a piston head 60 will force liquid in the compartment through a pipe section 190 which communicates with one of the inlets 142 in the assembly 132. The pressure of the liquid will open the ball valve for passage of the liquid through outlet 144. The assembly 132 provides a connection for each of the dispensing compartments so that all of the ingredients for a particular drink will be delivered simultaneously with the mixture passing through the discharge spout 128 for collection in a suitable container.

The spring 192 positioned around the vacuum piston rod 102 results in return movement of the piston rod and selector plate assembly when the action of the vacuum pump terminates. The circuitry employed could include control means for providing a specific time for operation of the vacuum pump, or this could be controlled by the person using the construction if the vacuum action is removed when the finger is taken off the push button 156.

- The springs 84 in the dispensing compartments provide for return movement of the piston heads 60. This return movement creates suction in the compartments which unseats the ball 42 for that compartment thereby drawing in a fresh supply of liquid. It will be noted that the liquid supply for a particular dispensing operation includes a liquid in the pipe section 190 as well as the liquid in a dispensing compartment. The ball valves associated with the assembly 132 prevent leaking.

Once a drink has been received in a container, the mixing means provided by operating push button 156 may be employed. It will be appreciated that this is an alternative arrangement applicable for certain types of drinks.

If desired, a counter may be associated with the switch 158 so that the number of drinks obtained with the construction can be determined at any given time.

It should be noted that the angular deployment of the different ingredients is a rigid answer statistically inseparable from the radial line along which the tappet arms 86 are located, as well as the angular and radial deployment of the pins 88 and their lengths. All these physical elements are rigidly linked to the number and proportions of ingredients necessary to produce particular drinks.

It will be appreciated that there are an infinite number of possibilities from the standpoint of angular deployment of the various ingredients, the locations of 'The readout of the computer will then provide information which will enable one to deploy the ingredients I and tappet arms, and to position and select the pins, so
